Key Features :
Compatible with 64bits games/apps
FXAA integrated without the need of an external DLL
New effects liike film grain and blur/bloom
Effects are separated from SMAA/FXAA to avoid artefacts
No more exotic file locations, everything should be dropped in the executable folder of the game/app
Somewhat better compatibility (more games supported) : DX9 all the games that use swapchain:
present now work with SweetFX, Farcry3 now works in DX11
Better performance for DX9 (DX11 performance is the same as MrHaandi's)
Better screenshot naming (app name + date & time as part of the filename)
Key mapping fully integrated in the SweetFX_settings.txt file
Ability to load external d3d9 wrapper (much like ENB proxy)
Ability to completely disable antialiasing and only use SweetFX shaders
Source-code, now we have one : )
Update 2013-06-01 :
Fixed compatibility issues (Grid 2, Dota2, Black OPS 2...)
Added gaussian blur, bloom, (costly) unsharpmasking for DX10/11 as well
